. i i ll@ WILLIAM NORTON AYERS, JR., or FORT SMITH, anxalvses.`

To all whom it may concern- Be it known that I, NILLL-iar N. Armes, Jr., ay citizen of the United States, residing at Fort Smith, in the county of Sebastian and State of Arkansas, have invented a new andiuseful Valve, of which the following is a specification.

This invention relates to an improvement in valves for gas engines.

rlhe primary 'object of the present invention is`to provide a gear driven rotary valve member which will periodically bring the opening in the engine cylinder in register with an exhaust port and a fuel intake.

A further object of the invention is to provide a valve member which completely embraces the engine cylinder, the gas prior to 'being introduced withinthe engine cylinder passing around the same, thus being heated-before its ent/rance to the cylinder.

lll/lith the foregoing and'other objects in view which will appear as the description proceeds, the invention resides inthe combination and arrangement o f parts and in the details of construction hereinafter described and claimed,l it being understood' that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed withoutdeparting from the spirit of the invention.

1n the drawings- Figure 1 is a transverse section. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a section on the line of Fig. 1, and Fig. 4'is a detail view of a portion o'f the rotary valve member.

.Tn the drawings, l0 designates the engine cylinder which is provided with the usual jacket 11. The cylinder 10 is provided with a port 12 which serves as both a fuel intake and an exhaust port, the same being alternately brought in register with the fuel sup ply and with an exhaust pipe 14. The rotary valve member 15 completely embraces the cylinder, said valve member being substantially U-shaped in cross section, being provided with side walls 16 and 17 and the intermediate portion 18, the latter being provided with a downwardly extending flange 19 which is provided with gear teeth 20, the under faces 21 of the member 18 being formed with a ball race 22, the flange and ball race lbeing formed independent of the valve and secured to the same. The annular member 15 is formed with a passage 24 which extends entirely through the walls Specification of Letters Patent.

1.6 and 17, said passage being maintained between the tv alls by the connecting hood 25. The wall 1i' is provided with an opening .26 which communicates with the space between the walls 1G and 17, the passage 24 serving as an exhaust passage and the passage 26 admitting fuel to the cylinder. The rotary member 15 rests within the housing 27 which is bolted or otherwise secured to the engine casing, the exhaust'pipe 14 extending within one wall of the housing, and the fuel intake 28 extending within the end portion of the housing, the fuel intake communicating with the space between the walls 16 and 17. The upper edges of the walls 16 and 17 lie flush with the portion 29 of the housing and effect a gas tight joint therewith, so that the gas will be prevent-ed from escaping between the edges of thesaid side walls 16 and 17 and the housing 29. The downwardly extending flange 19 which is provided with teeth 2O meshes with a gear 3() which is driven by the engine, thus properly timing the registeringV of the exhaust port and intake with the opening 12in the cylinder.

v Disposed immediately beneath the interlnediate portion 18 of the annular member 15 is a ring` 31 which is formed with a ball race 32, corresponding to the ball race 22 on the under face of the member 18, the balls 33 being interposed between the base 18 and the ring 31, thus facilitating the rotation of the annular member.

The gear 30 imparts movement to the annular member, the gas intake and exhaust being periodically brought in register with the opening 12. Gas enters through the intake 28, the space between the walls 16 and 17 being at all times filled with gas and the rotary valvemember practically serving as a jacket for the engine cylinder. Thus the gas is heated before the same is introduced to the cylinder, the advantages of this construction being clearly apparent.

It will be noted that various changes may be made in the drivingmechanism and in the positioning of the exhaustv passage 24 and the gas opening 26 in order to vary the time of registering of the ports with the centric of the engine cylinder and adapted to rotate about the axis thereof, said cylinder provided with an aperture therein forming a fuel inlet and exhaust port, Said annular member provided with an aperture in one wall thereof adapted to bring said hollow annular member into communication `with said cylinder aperture, a hood extending through the side walls of said annular hollow member adapted to bring said cylinder aperture and an exhaust pipe into communication, and means for rotating said hollow annular member. t

9.. The combination with an internal oombustion engine cylinder of a hollow annular member embracing the side walls of said cylinder, said hollow annular member adaptlrotatably mounted member embracing the side walls thereof, an 'aperture extending through the side walls of said cylinder, said hollow annular' member provided with an aperture extending through one wall thereof adapted to bring said hollow annular inember in communication with the said cylinder,

and means for.. introducing gaseous fuel within said hollow annular member, a passage extending through said hollow annular member and adapted to bringA said cylinder into communication with an exhaust pipe, said gaseous fuel adapted vto act as a cooling medium for the said cylinder duringv its passage through said hollow annular membcr and said cylinder adapted to act as a heating moans for the said gaseous fuel.

In testimony that I claim the foregoing as my own, I 'have hereto affixed my signature in the presence of two witnesses.
